Alright so two CPUs failing in the same system has gotta be strange; mobo issue?

Secondly, what BIOS settings should I be using to run safely? Is XMP/whatever the AMD equivalent is safe? If I don't run XMP then my RAM runs at way below spec (for the stick) default speeds.

Anyone know of a good guide for this stuff?

I have the same CPU in my primary system, and if you can afford it, it’s so choice.

A big surprise for me, having owned both a Ryzen gen 1 & 3 previously, was that this time my system posted without me needing to flash my BIOS or play around with various RAM configurations. Felt like magic.

Last Intel desktop CPU that I bought was Pentium 133Mhz. It was also my first PC. Never again ratio of performance to price in my preferred price range favored Intel.

You skipped the whole Bulldozer generation?

I've never bought server CPUs. I think I had some Athlon along the way. Some K6, I think. I don't remember all of them. Now I have some Ryzen. For the next build I'm finally eyeing server grade processor and of course it's going to be a Threadripper.

It's interesting how Intel has been surviving in smaller and smaller market niches these days:

  - cheap ULV chips like N100, N150, N300
  - ultrabook ULV chips (I hope Lunar Lake is not a fluke)
  - workstation chips that aren't too powerful (mainstream Core CPUs)
  - inexpensive GPUs (a surprising niche, but excruciatingly small)
AMD has been dominating them in all other submarkets.

Without a mainstream halo product Intel has been forced to compete on price, which is not something they can afford. They have to make a product that leapfrogs either AMD or Nvidia and successfully (and meaningfully) iterate on it. The last time they tried something like that was in 2021 with the launch of Alder Lake, but AMD overtook them with 3D V-Cache in 2022.

I feel like both Intel and AMD are not doing great in the desktop CPU stability department. I made a machine with a Ryzen 9900X a while back and it had the issue that it would freeze when idling. A few years before I had a 5950X that would regularly crash under load (luckily it was a prebuilt, so it was ultimately fixed). When you do not have a bunch of components ready to swap out it is also really hard to debug the…

I have a 5950X system that will just randomly shut down, I've RMA'd the CPU, tried swapping the RAM, GPU, PSU and the motherboard in different combinations. I cannot track down a specific issue and it just won't be stable. I've given up and decided to discard the PC of theseus and build a new one -_-.

Try enabling PBO and finding a setting for the curve optimizer that works for you, each CPU is different but -10/-15 is generally achievable - should reduce temperatures across the board and potentially give you some more performance.

The problem is that stable curve optimizer settings can vary hugely across cores I had differences of like 20 or more between different cores... i.e. one core might work fine at -20, the other maybe only at +5.

Most definitely - you should always do your own stress testing with your specific CPU (and system) to find out what's stable.

And while all core CO might not be optimal, based on personal experience and what I've seen across multiple enthusiast communities, more often than not you can get an worthwhile improvement to temps/perf with an all core CO.

That being said, there are certainly ways to find and set the best CO values per core, but it will certainly take more effort, stress testing and time.

AFAIK most (if not all) business laptops AKA Dell are intel based? Also I believe they are still big in the server market.

I'm not sure whether a "Dell Pro 16 Plus" is considered a "business laptop" (although I think so), but I'm using one right now and it has an AMD Ryzen AI 5 Pro CPU inside.

If OP's CPU cooler (Noctua NH-D15 G2) wasn't able to cool down his CPU below 100C, he must have been (intentionally or unintentionally with Asus multi core enhancement) overclocked his CPU. Or he didn't apply thermal paste properly or didn't remove the cooler plastic sticker? I have followed his blog for years and hold him in high respect so I am surprised he has done that and expected stability at 100C regardless of…

The cpu temps are one thing, but if - as you said - even a beast like the D15 G2 has it pegged at 100C, this very much sounds like bad ventilation and other parts of the system being toasted as well - VRMs in particular, for which the "PRIME" (actually being the low-end series) mainboards from Asus, as used here, don't exactly have a stellar reputation.

And yeah, having Arrow Lake running at its defaults is just a waste of energy. Even halving your TDP just loses you roughly 15% performance in highly MT scenarios...

I can't comment on the quality question, but for memory bandwidth sensitive use cases, Intel desktop is superior.

The last 15 years, servers has gone from 3x memory channels to 12x, while desktop still only have 2x memory channels. It is by far the biggest bottleneck today.

15 years ago a server CPU had twice as many cores as a desktop CPU. Today a server CPU has about eight times as many cores.
